[Story] Use textarea for some properties of the Project

[halsk]

Goal:

As a project leader, I want to write details so that I can share more information about my project.

Tasks:

1. Use textarea for project editing view

• What todo
• Problems
• Targets
• Needed help

Currently, Editable of Chakura UI is used for the page, and the Editable is not support textarea input.
But there is a new pull request for covering it. Maybe we can wait until the pull request is merged.

If possible, it is great if Markdown is supported for the What todo field.

Acceptance Criteria:

• Use textarea for the properties

If possible, it is great if Markdown is supported for the What todo field.

It's also good to provide WYSIWYG editor, especially for the people who're not familiar to Markdown
